Below 24.5K, Ne is a crystalline solid with an FCC structure. The interatomic interaction energy per atom can be written as 12 E(r) = -28 14.45 - 12.13 (e V/atom) where & and o are constants that depend on the polarizability, the mean dipole moment, and the extent of overlap of core electrons. For crystalline Ne, & = 3.121 x 10-3 eV and 0 = 0.274 nm. a. Show that the equilibrium separation between the atoms in an inert gas crystal is given by ro = (1.090)o. What is the equilibrium interatomic separation in the Ne crystal? b. Find the bonding energy per atom in solid Ne. C. Calculate the theoretical density of solid Ne (atomic mass = 20.18)
